I wish to restore my Wii to it's clean state and start all over. It's in a mess right now as I'm not sure what's in it and stuff, HBC and USBLoader are working fine. But I just need it to feel 'clean'.

While 4.2 was fairly thorough, it isn't perfect. For a truly virgin wii, you'd also need to delete IOS250 and uninstall cIOSCORP if installed. If he wants a quick clean job an update will do fine. If he wants a perfectly virgin wii, not the way to go.

For an "as close to fully virgin as they come" wii, best way is to:
* Uninstall cIOSCORP if installed (not likely, but never hurts to mention it)
* Use Wad Manager or AnyTitleDeleter Mod to uninstall any custom channels or pirated VC/WW (never remove IOSes or system menus).
* Disable preloader hacks/startpatch. (Remove preloader too, if not planning to update)
* Use AnyTitle Deleter to delete cIOSes (IOS202,222,223,249,250).
* Delete any save exploits (Indiana Pwns, Twilight Hack)
* Run hackmii installer from homebrew channel, and uninstall everything included in it.
* (Optional) Update wii.
* (Optional) Format wii to remove homebrew channel from logs.

Sorry but the format action from the Wii setting what really do? If you backup all your saves and then format...Isn't gonna clean everything?

It's not a good way to remove hacks, leave it at that. Honestly learning what you did on your Wii and individually getting rid of them would be the best way to get rid of stuff. And starting over is a kinda dumb reason to do it in most cases. Everything pretty much just reinstalls over eachother. Just redo everything and you should be fine anyways.

You can check this with free blocks it should have FREE BLOCKS (should be) = 2170/2169 on a virgin Wii.

I normally clean everything manually with nand clean etc, then format the Wii, but this can cause problems for some people.

Just note virgin Wii = 2170 blocks free

Don't IOS install to some of those NAND blocks?

if so, thats only true on a certain version and certain region.

some people have stub IOS version installed, others have no stubs

IOS, System Menu, some Nintendo channels, message board etc all use a reserved space iirc. (meaning it doesnt affect the free blocks you see in Wii settings)
Shared contents don't so a format will free this space.
An old 3.0 Wii or a freshly updated Wii to 4.2 should have 2170/2169 blocks free if it is clean.
